<p>A thermal insulation liner is provided for a chromatograph oven. The liner is moulded as a single bucket-shaped component (1) from ceramic fibres, typically alumino-silicate, bound together with an inorganic binder. The heat capacity and thermal conductivity of this material are both very low. The inner layer of the oven can be rapidly cooled for fast throughput of analyses and there is low risk of hand burns when changing chromatograph columns. The inner surface is moulded as a smooth shape, assisting the flow of circulated air and thereby reducing hot spots. Thermal insulation for the injector and detector of the chromatograph are also moulded in together with entry holes and mounting points (3, 4, 5, 6) to enable an inexpensive, easily assembled oven and chromatograph to be produced.</p> |
